In the ${}_{}{}^6{}_{}{}^{}\mathrm{Li}({}_{}{}^3{}_{}{}^{}\mathrm{He},p){}_{}{}^8{}_{}{}^{}\mathrm{Be}$ ($0^{+}$,$2^{+}$) reaction, the experimental results of the differential cross section and the polarization are fairly well described by a cluster point of view in which, instead of two-nucleon transfer, a deuteron transfer is a dominant process. The optical-model parameters for $p-{}_{}{}^8{}_{}{}^{}\mathrm{Be}$ are also investigated.
